3.1 Precautions
This section describes cautions before starting disassembling and
assembling this product. Make sure to read the precautions below before
starting.
3.1.1 General Cautions in operation
General cautions for disassembling and assembling this product are
provided below. Cautions for each procedure are provided in its
corresponding section. Make sure to refer to them before starting.
Do not touch the lamp or the parts around it. They are extremely hot
even after the cooling down operation completed. If any maintenance
work inside the projector is necessary soon after the projector is in
operation, leave the unit until it becomes cool enough before performing
maintenance work.
Never use the air blowers such as a lens cleaner that contains flammable
gas in repair/maintenance work.
Do not disassemble any components not as specified in this Service
Manual.
The Optical Engine, the circuit boards are very sensitive to static
electricity; therefore, be sure to take appropriate measures to prevent
static destruction such as to place them inside static-proof bags once they
have been removed from the projector.
The Optical Engine is very sensitive to vibration and shocks; therefore,
make sure to handle it with care.
The speaker unit contains a permanent magnet; therefore, make sure to
keep it away from any storage media such as floppy disks or magnetic
cards.
Be careful not to drop a metal part such as a screw, a washer, or a clip
into the inside of the product. If such cases should occur accidentally,
never turn on the power supply until all the dropped parts are found and
removed.
When carrying out any of the following operations, check that there is no
dust or dirt on any component or on any glass surface before installation.
If any contamination is found, clean it off using isopropyl alcohol.
Optical Engine removal
Lamp removal
When the projector is disassembled, the dust in and around parts (such
as those on the fans or air filter) may get transferred to other parts such
as the R, G and B light valves which are the central part of the display
mechanism. This may have an adverse effect on the quality of projected
images. Be sure to check whether any of the parts are dusty or dirty, and
use a vacuum cleaner to clean them first before carrying out disassembly/
reassembly work.
After reassembling the product, check the following before turning the
power on. All the parts and screws are installed and secured to the
proper positions. No cables are caught in the metal frames.
For this projector, a calibration is performed for the “Screen Fit”
function at the factory shipment. If the “MA Board (Assy)” or later in the
flowchart is disassembled for repair, the adjusted values may be
misaligned; therefore, restart the projector and check for abnormalities
in the functionality or the projected image.
